Saturday, May 30, 2026 will be marked by a time split in two opposing realities. While the thermometers will shoot again until they leave values that border the 40 degrees In the Guadiana and Guadalquivir basins, the State Meteorological Agency warns of a less visible but equally dangerous phenomenon: the possible appearance of “dry storms” in several areas of the center of the peninsula.
The notice, included in the prediction official for that date, reflects that the dominant atmospheric stability will begin to break down in the afternoon with the emergence of abundant cloudiness from evolution in the interior.
Mercury soars in southwest valleys
The episode of exceptional heat that has enveloped the closure of May will add a new chapter on Saturday. The detailed prediction that maximum temperatures will exceed 34-36 degrees in most of the interior of the southern half of the peninsula and in the depressions of the northeastern third, and that the most extreme values will be concentrated in the plains of the Guadiana and Guadalquivir, where the maximum temperatures will be exceeded. 38 degrees.
The thermal rise will be especially noticeable in Andalusia west and on the coasts of Alboranwhile in Balearicsthe northern third and the eastern façade the maximums will experience relative relief as they descend. The minimums, for their part, will gain strength in the southern half of the Peninsula and will maintain tropical nights with records above the 20 degrees in the southwest quadrantthe Mediterranean coast and the depressions of the northeast.
When the sky threatens but does not wet
The counterpoint to the heatwave will come with the growth of evolution clouds in the mountains of the center and northeast. The AEMET predicts storms and showers that may be locally strong and be accompanied by hail and very strong gusts of wind in the Pyrenees and in the Iberian area.
But the focus is also on what may happen in other regions of the center of the peninsulawhere the organism contemplates the formation of dry storms. It is a phenomenon in which precipitation evaporates before hitting the ground, leaving as the only visible trace intense electrical activity and, above all, sudden gusts of wind that can exceed the 80 or 90 kilometers per hour without a single drop alerting of its arrival. These gusts associated with dry storms represent a added risk for circulation and for outdoor activities, and explain why the AEMET has decided to underline the warning in its prediction for Saturday.
The wind, furthermore, will blow with strong intervals and possible streaks very strong in the Canary Islands, where the trade wind will set the tone, while in the Strait a moderate lift will prevail and on the Galician and Cantabrian coasts the north and west will dominate respectively.
In the rest of the country the day will start with light windalthough it will intensify in the afternoon coinciding with the development of the storms, which adds an extra factor of instability to an afternoon in which heat and atmospheric electricity will compete for prominence. The AEMET insist in which temperatures will remain at values elevated for the time, but the real challenge for those planning evening activities in the center of the peninsula will be reading a sky that can roar loudly without letting a single drop fall.
